'1'0 aZZ whom it may concern.-

Be it known that I, JOHN B. JONES, a citizen of the United States,residing at Battle Creek, county of Calhoun, State of Michigan, haveinvented a new and useful Spring Bed- Bottom, of which the following isa specification.

This invention relates to that class of spring bed-bottoms the upperwire fabric of which is sustained by spiral springs; and it has for itsobject the below described and claimed construction and novelassociation of parts.

In the drawings forming a part of this specifieation,Figure1 is a sideelevation with parts in section 011 dotted lines 3 3 in Fig. 2. Fig. 2is a plan view with one side broken away and showing half of thebed-bottom; Fig. 3, a section of parts on line 1 1 in Fig. 2. Fig. 4 isan enlarged plan of broken details, showing a change in construction;and Fig. 5 is a plan View with center of wire fabric broken.

Referring to the lettered parts of the drawings, A are the side rails, Bthe head-rail, and B the foot-rail, of a rectangular frame designed,when in use, to be placed in a bedstead in the ordinary manner of springbedbottoins. The wire fabric, 0, is attached'at each end to the endrails. The occupant of the bed of course lies upon this fabric, or,rather, upon the mattress which this fabric supports.

At D are a series of metal straps, which are more or less elastic,whether of iron or steel. There are two sets of these straps in a bed.Fig. 2 shows one of the sets. The straps are jointedly attached to thefoot-railB by hooks 0', which hook into a hole in the end of saidstraps, the other end hooking into the eye of the eyed screw c, whichadjustably screws into the rail B. The same eyed screws are in theheadrail B, and spiral springs a, having a hook at the end, detachablyhook into the eye of said screws e and into one of a series of adjusting-holes in the ends of the straps D. Thus the straps D maybeallowed to less or more, according to the desired results belowexplained, either by means of the eyed screws or by hooking the springsa. in different holes in the ends of the straps D, or both, ifpreferred. The important object, however, of screwing the screws c farher in or out is to secure the proper normal tension on the straps andfabric, 0, when constructing the bed-bottom. A set of separated bars, f,bearing upright spiral springs Z), are located on the straps Dtransversely thereto. The springs I) support the center of the fabric,C. The bars f are attached together by bars S, and the whole isadjnstably attached to the straps D by means of the metal loops orstaples n, Fig. 3, which loosely surround said straps D. By this meansthe bars f and their springs b can readily be drawn toward the head orthe foot of the bed to support the fabric, O, at the particular placedesired, according to the fancy or needs of the occupant of the bed.

In the complete bed, as shown by Fig. 5, there are two sets of thetransverse slats f, shown located end to end, their contiguous endsbeing a little separated from each other.

The bed-bottom can be madelongitudinally higher in the center by hookingthe hook of the springs a in a hole farther from the end of the twoinner straps, D, so as to raise said straps or cause them to sag lessthan the others, and this action will of course raise the fabric, 0, atits longitudinal center. The rea son of this is that the inner end ofeach set of slats or bars f will be raised, which action will. raise thesprings 1) near said ends up against the longitudinal center of the wirefabric. By tightening or raising the straps D of one side by means ofsuch adjustments, which action will of course raise and tighten ortension one side of the bed more than the other, the bed is adapted forthe use of a hear y and a light weight person. For the reason that oneset of transverse bars y" will rise independently of the other set onthe other side of the bed, and as the wire fabric is continuous from oneside of the bed to the other over both sets of transverse slats f, Fig.5, and flexible, it will. yield suiiiciently at its longitudinal centerfor the purpose.

If preferred, the adjustment or tension 0% the straps D and springsmaybe accomplishet by using a swiveled buckle, u, swiveled to the endrail of the frame and screw-connected to center of the fabric, and thestaples or loops the straps D, as at d, Fig. 4.
